Application filed February 10, Serial No. 607,759.

T 0 all whom it may concerm Be it known that I, FERDINAND BUR- orrnn'rz, a citizen of the United States, and

resident of the borough of, Manhattan, city, county, and State of New York, have madapted to receive the usualtie rods and 1I1-&- 15 terial such ascement or thelike for the blocks into a monolithic structure and binding for forming reinforced load carrying beams or girders.

A further object of my invention is to provide a hollow block having open ends and provided on one side with a recessed extension for forming the said intersecting channels, the blocks being preferably arranged in pairs withthe extensions of one pair of blocks arranged adjacent to and closing the open ends of the next adjacent pairs of blocks. In other words in my improved construction the blocks are positioned in sets of two, the axes of adjacent sets extending at right angles to each other,

so that each set of blocks will lie between and close the open ends of two spaced and alining sets of blocks and prevent the cement or other binding material placed be tween the blocks from reaching the interior thereof.

My invention will befully described here-1 inafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings in -which- Figure 1 is a sectional elevation of a portionof my improved floor or ceilingv construction; Fig. 2 is a plan view thereof; Figs. 3,, 4 and 5 are crosssectional views illustrating three different forms ofmy improved block, Fig. 6 is a horizontal section of one block showing ameans for closing the.

one open end of the end blocks in a row and Fig. 7 is a cross section thereof on the line 7-7 of Fig. 6 looking in the direction of the arrow. r j I My improved blockcomprises a hollow body portion A having opposite open ends and provided or supplied on one side with a recessed L sha aed extension a forming a channel 1;. The extension ai's preferably but not necessarily formed integral with the body portion A and extends parallel with the axis" thereof. The wall of each body portion A on the side opposite to that on which the recessed extension (1 is locatedis preferably inclined as indicated at c in Fig. 1. In constructing a floor or ceiling according to my present invention. the blocks are set in pairs on i a temporary scaffolding or centering, with thelinclin'ed walls a opposed to or adjacent to each other as shown in Fig. 1. Each adjacent set or pair of blocks in each rowis positioned with the axes thereof extending at right angles to each other, so that the extensions a of one set of blocks will close the open ends of' the two sets of blocks arranged to either side thereof. Inother words the blocks in pairs or sets are arranged in parallel adjacent'rows, the sets of blocks in each row having their axes ex tending alternately at substantially right anglesto eachother, so that the recessed extensions "a of each set of blocks serve to close the open ends of the two adjacent sets of blocks and in turn have their open ends closed by the extensions a of the cooperating sets of blocks in the next adjacentrows. lVith this varrangement which is clearly shown in .Fig. 2 of the drawings, the recessed extensions (1 of each alternate set of blocks aline-with each other and form continuous channels I) which extend throughout the floor or ceiling and intersect each other. These channels?) serve to accommodate the usual reinforcing or tie rods cl and are also adapted to receive the cement. concrete or other material 6 for securing the blocks together in a monolithic structure and wh ch forms intersecting concrete or other load carrying beams or girders.

The extensions a in addition to forming the channels balso serve to position the sets of blocks and to properly space them apart so that noparticular skill or care is required in constructing the floor or ceiling. The ex-. tensions a are further preferably of a length corresponding to the outside wid th of two body portions, so that each extensiona in the finished structure will extend across one openend of two body portionsA form ing a s'et.- .It will be seen that whenthe blocks are set up as described the opposed ends of adjacent extensions a are spaced from each other and form spaces f as clearly illustrated in Fig. 2. The temporary scaffolding or centering forms a temporary bottom for these openings 7 so that the material will enter and fill said openings but will not fall through the same and after becoming set will serve as a key or projection to' pre-.

cement or other material 6 forming the beams or girders also enters the spaces be-.

tween opposed walls 0 of each set of blocks so that nodry joints exist between the blocks in a set in the finished structure.

It is sometimes very desirable to interrupt the concrete or other material instead of having the same in the form of a complete slab as in Figs. 1 and 2, for which reason I may use the form of blocks shown in Figs. 3, 4 and 5. In Fig. 3 the blocks A are provided with integral projections g which extend throughout the length of each block but do not extend throughout the entire width thereof. In Fig. 4 the projections g are formed by merely thickening the upper wall of the body portions A and in addition are provided with ventilating channels 9 which extend lengthwise thereof. In Fig. 5 the projections g extend lengthwise of the body portion A and are spaced from each other by a dovetail groove in which a wooden or other sleeper g is secured, This is a very useful and convenient form when. it is desued to cover the complete floor or ceiling with a covering of woodor with other material as the said projections 9 not only interrupt the binder but the said sleepers 9 provide a ready means in which fastening means such as nails or screws'for securing the covering in position may be driven. These last three forms of block are otherwise the same as the form shown in Figs. 1 and 2 and may be set up and used in exactly the same way.

In instances where the end blocks of a row owing to their relative location are spaced from the walls of the building and have their open ends exposed I provide a U- shaped closure 71,, the members it of which extend into the body portion A of the block. In order to prevent this closure from being forced entirely into said body portion I may provide the blocks intended for the ends of a row with ribs or partitions 72, extending 6O lengthwise of the said body portion. These partitions serve to limit the inward movement of the closure 72. and to position the same so that the transverse wall thereof is not flushwith the block end but projects beyond the same, and is thus locked against 7 terial.

any movement by the cement or other ma- This closure 72. is of a size-to completely cover the open ends of the blocks wherever necessary and prevents the material from entering the interior of the bodies A.

While I have shown two ribs or partitions in Figs. 6 and 7 I desire it to be understood that in some cases a single central rib will be suflicient for the purposes intended, or stops of other form may be provided. Furthermore the rib or ribs need not be continuous and extend throughout the length of the body A but may be interrupted at a point within the body portion A.

The various forms of blocks used in my improved floor or ceiling construction are easily and cheaply madeand are very light and yet capable of resisting heavy strains and together with the beams orgirders formed by the cement, concrete or other material in the channels If results in a structure capable of sustaining heavyloads, the reinforced concrete or other girders themselves acting as load carrying elements in addition to binding the blocks together in a monolithic structure. The said blocks may be made of any suitable material but are preferably made of fireproof material such as clay, concrete, terra cotta or the like. Various changes in the specific forms shown and described may be made within the scope of the claims without departing from the spirit of my invention.

I claim:
